BIG3 Tracker is a focused weight-training log built around the three lifts that matter most: Bench Press, Squat, and Deadlift. TRACK YOUR LIFTS Log weight, reps, and sets for each workout in seconds. Multiple sets in one session are combined into a single, clean entry — no clutter, just your numbers. SEE YOUR PROGRESS A progress chart for each lift shows your trend over any time range — 1 month, 3 months, a year, or a custom range you choose. Your estimated one-rep max (1RM) updates automatically using the Epley formula. KNOW YOUR LEVEL Enter your body weight and gender to unlock an at-a-glance strength level chart — Novice, Intermediate, Advanced, and Elite Athlete — for each lift. Get a celebration message the moment you level up or set a new personal best. TRAINING SUGGESTIONS, NO GUESSWORK Pick a goal — Strength, Hypertrophy, or Endurance — and get an instant weight/reps/sets suggestion based on your estimated 1RM. No AI, no network required — just straightforward numbers you can act on immediately. BUILT-IN REST TIMER A rest timer with quick presets (60/90/120/180s) or any custom duration, right on the record screen, with a sound cue when your rest is up. YOUR UNITS, YOUR CHOICE Switch freely between kilograms and pounds — the app adapts your body weight, charts, and level chart to whichever you prefer. FREE TO TRY Your first month is free. After that, unlock unlimited new record entries for a low monthly subscription. Viewing your existing records, charts, and level chart always stays free. No ads. No clutter. Just your BIG3 numbers, tracked simply.
